COMBINED MUSIC-STAND AND MUSIC-LEAF TURNER.

SPECIFICATION forming part of Letters Patent No. 677, dated July 2,1901.

Application filed October 24:, 1900. Serial No. 34,190. (No model.)

To all whmn it may concern:

Be it known that I, OTTO CHARLIE ZERCK, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented new and useful Improvements in a Combined Music-Stand andMusic- Leaf Turner, of which the following is a specification.

This invention relates to new and useful improvements in combinedmusic-stands and music-leaf turners; and the primary object thereof isto provide a holder which may be adjusted to sheets of various sizes andhaving a leaf-turner which may be readily operated by the performer. 7

With this and other objects in view the invention consists in certainnovel features of construction and combination'of parts,

which will be hereinafter fully described and claimed, and illustratedin the accompanying drawings, showing the preferred form of myinvention, and in which Figure 1 is a front elevation of the device.Fig. 2 is an enlarged vertical section through the base on line 2 2 ofFig. 1. Fig. 3 is an enlarged section through the base on line 3 3 ofFig. 2. Fig. 4 is'a plan view of the bellcrank lever and its operatingmechanism, showingits supporting-blockin section. Fig. 5 is an innerelevation of the operating-lever. Fig. 6 is a plan view of the base,showing the spring-strips, bell-crank lever, and the operating-lever inposition. Fig. 7 is an enlarged section through the lower end of thestandard.

Referring to the figures by numerals of reference, 1 is a preferablytubular standard which is reduced in thickness at its lower end,as at 2,and said reduced end is inclosed by a collar 3, having ears 4 extendingtherefrom in pairs, and within each pair is pivoted a leg 5 of theholder. Each leg is provided with a bayonet-like upper end 6, which isadapted to bear upon the reduced portion of the standard at a pointbetween the sleeve 3 and the shoulder 7, formed by said reduced portion,and a sliding sleeve 8 is mounted upon the standard and adapted toextend over the ends of the legs, and thereby hold the same in theposition shown in Fig. 1. It will be seen that when the sleeve 8 ismoved upward the legs will be free to swing inward, renderingthe devicemore compact.

A rod 9 is slidably mounted within the tubular standard 1 and is adaptedto be locked in adjusted position in any suitable manner, as by means ofa set-screw 10. A base 11, which is substantially L-shaped incross-section, is provided upon its rear face with a bracket 12, whichis adapted to receive the upper squared end 13 of the rod 9.

One or more spring-metal strips 14 are secured to the upright portion ofthe base at the center thereof and are provided at their free ends withpaper-clips 15, adapted to clasp the lower edges of the sheets of musicin position upon the holder. These springstrips are adapted to be bentbackward upon themselves and held in such position by one arm 16 of abell-crank lever. The second arm 17 of said lever lies within a plane inrear of the front strip 14, and the end thereof is adapted to rest at apoint adjacent to the lower edge of said strip.

A shaft 18 extends inward from the bellcrank lever and is journaledwithin a block 19, secured to the under surface of the bottom of thebase. A coil-spring 20 incloses this shaft and is secured at oppositeends to the block and shaft, respectively, and is adapted to hold thearm 16 of the bell-crank lever normally in the path of the strips. Agear 21 is secured to the rear end of the shaft 18 andmeshes with a rack22, formed at one end of a lever 23, which is pivoted to the side of theblock and extends forward to a point in front of the base 11. The frontend of this lever is enlarged, as at 24, so that the same may be readilydepressed by hand. A stud 25 extends laterally from the block 19 andserves to limit the downward movement of the lever 23.

' The substantially L shaped supportingstrip 26 is secured to the frontface of the upright portion of the base 11 and is provided with slots27, adapted to receive the paperclips 15, before referred to. Thisstrip, as well as the upright portion of the base 11, is provided with ahorizontally-extending slot 28, within which are slidably mounted pins29. Each pin is secured to one arm 30 of a lazy-tongs, while theremaining arm 31 is pivoted upon a stud 32, extending from the base,near one end thereof. It will thus be seen that a pair of tongs isarranged at each end of the base. Blocks 33 are formed with the pins 29and the studs 32, and a rod 34:, having right and left hand threadsextending from the center thereof, engages the sliding blocks and isrevoluble within the blocks of the studs This rod may be readily turnedby means of a head 35, formed at one end thereof. The opposite ends ofthe lazy-tongs are secured to a horizontallyextending strip 36, one armof each tongs being pivoted to said strip at one end thereof, while there maining arm is provided with a pin 37, which is slidably mountedwithin a longitudinally extending slot 38 within said strip.

Music is placed upon the supporting-strip 2G, and the strip 36 isadjusted vertically by turning the screw 34: in either direction, thereby causing the lazy-tongs to be extended or retracted. The spring-stripsltare then bent backward into the position shown in Fig. (5, and eachclip 15, extending through the slot 27, is placed into engagementwiththe lower edge of one of the leaves of the music. These spring-stripswill be held in this position by the arm 16 of the bell-crank lever, andwhen it is desired to turn a leaf of the music the end 24: of the lever23 is depressed. This will cause the shaft 18 to revolve, and will throwthe arm 16 out of the path of the front strip let. As soon as this armis removed from the path of said strip the remaining arm 17 will bebrought to a point in rear of the strip and will prevent outwardmovement of the remaining strips. As soon as the strip 14 is released itwill spring outward and will swing the clip 15 around into the remainingslot 27 within the supporting-strip 26. \Vhen the lever 23 is released,the bell-crank lever will be returned to its normal position by thespring 20, and as soon as the arm 17 of said lever drops out of the pathof the strips the remaining arm will arrive in position in front of thestrips and prevent movement thereof. It will be seen that this operationwill be repeated whenever it is desired to turn one of the remainingleaves.

\Vhen the holder is not in use, the legs 5 may be folded inward byraising the sliding sleeve 8. The base 11 can then be slipped off of thesquared end of the rod 9 and the lazy-tongs retracted, bringing thestrip 36 in close proximity to the base. The parts may then be storedaway, requiring but a minimum amount of space.

In the foregoing descriptionl have embodied the preferred form of myinvention; but I do not wish to be understood as limiting myselfthereto, as I am aware that modilica-- tions may be made therein withoutdeparting from the spirit or sacrificing any of the advantages of thisinvention, and I therefore reserve to myself the right to make suchchanges as fairly fall within the scope thereof.

Having thus described the invention, what is claimed, and desired to besecured by Letters Patent, is

l.
